Wireless Modem Card and Subsystem Overview

The Cisco high-speed point-to-point broadband fixed wireless system provides a fixed, dedicated
wireless linkfrom one site to another.This link deliversfull-duplex datainthe licensed MMDS band
(2.500 to 2.690 GHz), or unlicensed U-NII band (5.725 to 5.825 GHz).

The broadbandfixed wireless system consists of aCisco uBR7200 series universalbroadband router
(Cisco uBR7246 or Cisco uBR7223) and one or more wireless modem cards (see Figure 1), each
with a power feed panel (see Figure 2), and one or two wireless transverters (see Figure 3). (The
diversity option, which minimizes the effects of fading, uses two wireless transverters, one for each
of two antennas.)

The wireless modem cards are installed in a Cisco uBR7200 series router. Each modem card is
cabled to a power feed panel installed either in the same equipment rack as the router or mounted on
a wall. Cables from the power feed panel are attached to one or two wireless transverters, which are
installed on the antenna mast. The system is managed via a command-line interface (CLI) or
CiscoView. Figure 4 shows the connections between the components.

Wireless Modem Card and Subsystem Overview

Table 2 Wireless Modem Card LEDs
LED Function

Carrier LED Indicates the state of the radio link. When green, the radio link is synchronized and the line

protocol is up. When yellow, indicates loss of link synchronization.

Out of Service LED Indicates the service availabilityof the radio link. When yellow, the radio link is still up, butnot

available for use (typically in a test or loopback mode).

Minor Alarm LED When yellow, indicates the occurrence of a minor alarm in the radio subsystem. The link is

degraded and may need maintenance action or, one or more user-defined event thresholds have
been exceeded.

Major Alarm LED When yellow, indicates the occurrence of a major alarm in the radio subsystem. The link is

down.

Enabled LED When green, indicates that the wireless modem card is on, receiving power from the router

midplane, and enabled for operation. This LED remains on during normal operation of the
Cisco uBR7200 series router.

Power Feed Panel

The power feed panel provides DC power, transmit and receive IF signals, frequency reference, and
control signals to the wireless transverter. The unit contains circuit breakers for the DC power, as
well as secondary lightning protection circuitry for the control cables. Local or national codes may
require you to install primary lightning protection for the IF cable and the control cable.

The power feed panel consists of the following components:

• Power LEDs on front and rear panel

• Connector ports

— Coaxial cable connection to the wireless modem card and the wireless transverter (main and

— Control cable connection ports to the wireless modem card and wireless transverter (main

• Power ON/OFF breaker switches (main and diversity)

• DC power supply terminal block

• Ground lug

Warning This product requires short-circuit (overcurrent) protection to be provided as part of the

building installation. Install only in accordance with national and local wiring regulations.

Warning A readily accessible two-pole disconnect device must be incorporated in the fixed wiring.

Electrical Equipment Guidelines

Follow these basic guidelines when working with any electrical equipment:

• Before beginning any procedures requiring access to the chassis interior, locate the emergency

power-off switch for the room in which you are working.

• Disconnect all power and external cables before moving a chassis.

• Do not work alone if potentially hazardous conditions exist.

• Never assume that power has been disconnected from a circuit; always check.

• Do not perform any action that creates a potential hazard to people or makes the equipment

unsafe.

• Never install equipment that appears damaged.

• Carefully examine your work area for possible hazards such as moist floors, ungrounded power

extension cables, and missing safety grounds.

Preventing Electrostatic Discharge Damage

Electrostaticdischarge(ESD) damagesequipmentand impairs electricalcircuitry. ESDoccurs when
printed circuit boards are improperly handled and results in complete or intermittent failures

The network processing engine, I/O controller, port adapters, and wireless modem cards consist of
a printed circuit board that is fixed in a metal carrier. Electromagnetic interference (EMI) shielding,
connectors, and a handle are integral components of the carrier. Handle the network processing
engine, I/O controller, port adapters, and wireless modem cards by their carrier edges and handles;
never touch the printed circuit board when handling either component.
